What is conditional frequency, and how do you determine which value is the denominator?
pantera1 [17]
In the two-way table, It<span> is used to examine relationships between categorical variables. and the entries in the cells can be relative frequencies, that we known as "Conditional Frequency/distribution"

In order to determine the denominator, we add all the values in given column, and for second column,we add all the numbers in 2nd column, & it would be the denominator for each & every cell in that column.

If Scatter plot has no association, then it would not indicate any trends. It means, progression of number can't be formularized in a specific way, 'cause there is no relation between the numbers

Hope this helps!</span>

Find the solution set of the inequality<br> 4x-1&lt; 11.<br><br> PLEASE HEP I NEED THIS ASAP!!!!
maxonik [38]

Answer: x > 3

Step-by-step explanation:

In order to find x, we must isolate it first.

Add one to both sides. It's now 4x < 12.

Now we divide both sides by 4, remember that every time we divide or multiply we must flip the inequality symbol.

The final answer is x > 3
